After "AND" and after "OR" the QUERY has forgotten what it is all about.

I would also not know that it is about in any SQL / programming language.

if(SOMETHING equals "X" or SOMETHING equals "Y")

COLUMN NOT LIKE "A%" AND COLUMN NOT LIKE "B%"

This happens every time you insert/ update and you don't use single quotes. When the variable is empty it will result in that error. Fix it by using ''

Assuming the first parameter is an empty variable here is a simple example:

Wrong

nvl( ,0)

Fix

nvl('' ,0)

Put your query into your database software and check it for that error. Generally this is an easy fix

You need to pass it as an extra:

String easyPuzzle  = "630208010200050089109060030"+
                     "008006050000187000060500900"+
                     "09007010681002000502003097";

Intent i = new Intent(this, ToClass.class);
i.putExtra("epuzzle", easyPuzzle);
startActivity(i); 

Then extract it from your new activity like this:

Intent intent = getIntent();
String easyPuzzle = intent.getExtras().getString("epuzzle");

I found a way for this on the net

It demands a little bit of work, because it has to be done table by table. But anyway, I could copy the tables, data and constraints into a MS SQL database.

Here is the link

http://www.codeproject.com/KB/database/migrate-mysql-to-mssql.aspx

ACCESS_COARSE_LOCATION, ACCESS_FINE_LOCATION, and WRITE_EXTERNAL_STORAGE are all part of the Android 6.0 runtime permission system. In addition to having them in the manifest as you do, you also have to request them from the user at runtime (using requestPermissions()) and see if you have them (using checkSelfPermission()).

One workaround in the short term is to drop your targetSdkVersion below 23.

But, eventually, you will want to update your app to use the runtime permission system.

For example, this activity works with five permissions. Four are runtime permissions, though it is presently only handling three (I wrote it before WRITE_EXTERNAL_STORAGE was added to the runtime permission roster).

For the requestPermissions() function, should the parameters just be "ACCESS_COARSE_LOCATION"? Or should I include the full name "android.permission.ACCESS_COARSE_LOCATION"?

I would use the constants defined on Manifest.permission, as shown above.

Also, what is the request code?

That will be passed back to you as the first parameter to onRequestPermissionsResult(), so you can tell one requestPermissions() call from another.

I have one more solution, I think. I recently had changed my computer name so, after I couldn't connect still after trying all above methods. I changed the Server name.. Server name => (browse for more) => under database engine, a new server was found same as computers new name. This worked, and life is good again.

I would insert all the emails into a database (sort of like a queue), then process them one at a time as you have done in your code (if you want to use swiftmailer or phpmailer etc, you can do that too.)

After each mail is sent, update the database to record the date/time it was sent.

By putting them in the database first you have

1. a record of who you sent it to
2. if your script times out or fails and you have to run it again, then you won't end up sending the same email out to people twice
3. you can run the send process from a cron job and do a batch at a time, so that your mail server is not overwhelmed, and keep track of what has been sent

Keep in mind, how to automate bounced emails or invalid emails so they can automatically removed from your list.

If you are sending that many emails you are bound to get a few bounces.

This worked for me too, but with an addition (below).

protected void Page_Load(object sender, EventArgs e) {
  ScriptManager scriptManager = ScriptManager.GetCurrent(this.Page);
  scriptManager.RegisterPostBackControl(this.btnExcelExport);
  //Further code goes here....
}

I was registering a script on my button to click on another button after its event was finished processing. In order for it to work, I had to remove the other button from the Update Panel (just in case somebody faces the same problem).

Here's a one-liner that doesn't use/require the new job to be in a file:

(crontab -l 2>/dev/null; echo "*/5 * * * * /path/to/job -with args") | crontab -

The 2>/dev/null is important so that you don't get the no crontab for username message that some *nixes produce if there are currently no crontab entries.

I'd use head --bytes -1, or head -c-1 for short.

COMPANY_NAME=`cat file.txt | grep "company_name" | cut -d '=' -f 2 | head --bytes -1`

head outputs only the beginning of a stream or file. Typically it counts lines, but it can be made to count characters/bytes instead. head --bytes 10 will output the first ten characters, but head --bytes -10 will output everything except the last ten.

NB: you may have issues if the final character is multi-byte, but a semi-colon isn't

I'd recommend this solution over sed or cut because

• It's exactly what head was designed to do, thus less command-line options and an easier-to-read command
• It saves you having to think about regular expressions, which are cool/powerful but often overkill
• It saves your machine having to think about regular expressions, so will be imperceptibly faster

I found very good link for JSON: http://code.google.com/p/json-simple/wiki/EncodingExamples#Example_1-1_-_Encode_a_JSON_object

Here's code to add multiple JSONObjects to JSONArray.

JSONArray Obj = new JSONArray();
try {
    for(int i = 0; i < 3; i++) {
        // 1st object
        JSONObject list1 = new JSONObject();
        list1.put("val1",i+1);
        list1.put("val2",i+2);
        list1.put("val3",i+3);
        obj.put(list1);
    }

} catch (JSONException e1) {
    // TODO Auto-generated catch block
    e1.printStackTrace();
}             
Toast.makeText(MainActivity.this, ""+obj, Toast.LENGTH_LONG).show();

You can use ref.

import ChildForm from './components/ChildForm'

new Vue({
  el: '#app',
  data: {
    item: {}
  },
  template: `
  <div>
     <ChildForm :item="item" ref="form" />
     <button type="submit" @click.prevent="submit">Post</button>
  </div>
  `,
  methods: {
    submit() {
      this.$refs.form.submit()
    }
  },
  components: { ChildForm },
})

If you dislike tight coupling, you can use Event Bus as shown by @Yosvel Quintero. Below is another example of using event bus by passing in the bus as props.

import ChildForm from './components/ChildForm'

new Vue({
  el: '#app',
  data: {
    item: {},
    bus: new Vue(),
  },
  template: `
  <div>
     <ChildForm :item="item" :bus="bus" ref="form" />
     <button type="submit" @click.prevent="submit">Post</button>
  </div>
  `,
  methods: {
    submit() {
      this.bus.$emit('submit')
    }
  },
  components: { ChildForm },
})

Code of component.

<template>
 ...
</template>

<script>
export default {
  name: 'NowForm',
  props: ['item', 'bus'],
  methods: {
    submit() {
        ...
    }
  },
  mounted() {
    this.bus.$on('submit', this.submit)
  },  
}
</script>

Here is a solution I've found to enable the global terminal colors.

Edit your .bash_profile (since OS X 10.8) — or (for 10.7 and earlier): .profile or .bashrc or /etc/profile (depending on availability) — in your home directory and add following code:

export CLICOLOR=1
export LSCOLORS=GxFxCxDxBxegedabagaced

CLICOLOR=1 simply enables coloring of your terminal.

LSCOLORS=... specifies how to color specific items.

After editing .bash_profile, start a Terminal and force the changes to take place by executing:

source ~/.bash_profile

Then go to Terminal > Preferences, click on the Profiles tab and then the Text subtab and check Display ANSI Colors.

Verified on Sierra (May 2017).

Prepend the url prefix git+ (See VCS Support):

pip install git+https://github.com/tangentlabs/django-oscar-paypal.git@issue/34/oscar-0.6

And specify the branch name without the leading /.

In addition to grants, you can try creating synonyms. It will avoid the need for specifying the table owner schema every time.

From the connecting schema:

CREATE SYNONYM pi_int FOR pct.pi_int;

Then you can query pi_int as:

SELECT * FROM pi_int;

I have solved this topic with the solution I have found here: http://www.blackwasp.co.uk/SwitchConfig.aspx

In short what they state there is: "by adding a post-build event.[...] We need to add the following:

if "Debug"=="$(ConfigurationName)" goto :nocopy
del "$(TargetPath).config"
copy "$(ProjectDir)\Release.config" "$(TargetPath).config"
:nocopy

I just encountered and solve a similar problem.

First you should check the directory like other threads described. Then you can check whether the Build tool version matches your SDK version.

(e.g. for my project, in build.gradle file, you have:)

android { compileSdkVersion 21 buildToolsVersion "21.1.1" }

and then open you SDK manager, make sure you have the same version of sdk(21.1.1) installed in the selected directoriy:

If not, install it and restart Android Studio. It works for me.

I've also seen other guys saying run Android Studio as administrator would also help:

https://teamtreehouse.com/forum/i-am-getting-this-warning-message-rendering-problems-no-android-sdk-found-please-configure-an-android-sdk

use the keyword break instead of return

None of the solutions above worked for me.

The solution that finally worked for me was switching SSH client. GIT_SSH environment variable was set to the OpenSSH provided by Windows Server 2019. Version 7.7.2.1

C:\Windows\System32\OpenSSH\ssh.exe

I simply installed putty, 0.72

choco install putty

And changed GIT_SSH to

C:\ProgramData\chocolatey\lib\putty.portable\tools\PLINK.EXE

Inflater actually some sort of convert to data, views, instances, to visible UI representation.. ..thus it make use of data feed into from maybe adapters, etc. programmatically. then integrating it with an xml you defined, that tells it how the data should be represented in UI

You could make two forms with 2 different actions

<form action="login.php" method="post">
    <input type="text" name="user">
    <input type="password" name="password">
    <input type="submit" value="Login">
</form>

<br />

<form action="register.php" method="post">
    <input type="text" name="user">
    <input type="password" name="password">
    <input type="submit" value="Register">
</form>

Or do this

<form action="doStuff.php" method="post">
    <input type="text" name="user">
    <input type="password" name="password">
    <input type="hidden" name="action" value="login">
    <input type="submit" value="Login">
</form>

<br />

<form action="doStuff.php" method="post">
    <input type="text" name="user">
    <input type="password" name="password">
    <input type="hidden" name="action" value="register">
    <input type="submit" value="Register">
</form>

Then you PHP file would work as a switch($_POST['action']) ... furthermore, they can't click on both links at the same time or make a simultaneous request, each submit is a separate request.

Your PHP would then go on with the switch logic or have different php files doing a login procedure then a registration procedure

To convert a string into a date, the easiest way AFAIK is the dateutil module:

import dateutil.parser
datetime_object = dateutil.parser.parse("2013-05-07")

It can also handle time zones:

print(dateutil.parser.parse("2013-05-07"))
>>> datetime.datetime(2013, 5, 7, 1, 12, 12, tzinfo=tzutc())

If you have a datetime object, say:

import pytz
import datetime
now = datetime.datetime.now(pytz.UTC)

and you want chop off the time part, then I think it is easier to construct a new object instead of "substracting the time part". It is shorter and more bullet proof:

date_part datetime.datetime(now.year, now.month, now.day, tzinfo=now.tzinfo)

It also keeps the time zone information, it is easier to read and understand than a timedelta substraction, and you also have the option to give a different time zone in the same step (which makes sense, since you will have zero time part anyway).

You can use the click event and call your function or move your logic into the handler:

$("#bfCaptchaEntry").click(function(){ myFunction(); });

You can use the click event and set your function as the handler:

$("#bfCaptchaEntry").click(myFunction);

.click()

Bind an event handler to the "click" JavaScript event, or trigger that event on an element.

http://api.jquery.com/click/

You can use the on event bound to "click" and call your function or move your logic into the handler:

$("#bfCaptchaEntry").on("click", function(){ myFunction(); });

You can use the on event bound to "click" and set your function as the handler:

$("#bfCaptchaEntry").on("click", myFunction);

.on()

Attach an event handler function for one or more events to the selected elements.

http://api.jquery.com/on/

s is an uninitialized pointer; you are writing to a random location in memory. This will invoke undefined behaviour.

You need to allocate some memory for s. Also, never use gets; there is no way to prevent it overflowing the memory you allocate. Use fgets instead.

$ls -l `which sh`
/bin/sh -> dash

$sudo dpkg-reconfigure dash #Select "no" when you're asked
[...]

$ls -l `which sh`
/bin/sh -> bash

Then it will be OK

For iOS 3.2 and above: Use the methods provided by several above, which are:

1. Add your font file (for example, Chalkduster.ttf) to Resources folder of the project in XCode.
2. Open info.plist and add a new key called UIAppFonts. The type of this key should be array.
3. Add your custom font name to this array including extension ("Chalkduster.ttf").
4. Use [UIFont fontWithName:@"Real Font Name" size:16] in your application.

BUT The "Real Font Name" is not always the one you see in Fontbook. The best way is to ask your device which fonts it sees and what the exact names are.

I use the uifont-name-grabber posted at: uifont-name-grabber

Just drop the fonts you want into the xcode project, add the file name to its plist, and run it on the device you are building for, it will email you a complete font list using the names that UIFont fontWithName: expects.

from itertools import product 
list_vals = [['Brand Acronym:CBIQ', 'Brand Acronym :KMEFIC'],['Brand Country:DXB','Brand Country:BH']]
list(product(*list_vals))

Output:

[('Brand Acronym:CBIQ', 'Brand Country :DXB'),
('Brand Acronym:CBIQ', 'Brand Country:BH'),
('Brand Acronym :KMEFIC', 'Brand Country :DXB'),
('Brand Acronym :KMEFIC', 'Brand Country:BH')]

According with the HTTP/1.1 standard, the shared IP hosted site can be accessed by a GET request with the IP as URL and a header of the host.

I know this is an old post, but I ran into this same issue with my VMs. Log into the VM and go to Control Panel > System and Security > Windows Firewall > Allowed Apps. Then check all of the boxes next to "File and Printer Sharing" to enable file sharing. This should allow you to ping the VM. The screenshot below is from a 2016 Windows Server but the same method will work on older ones.

By using itemStateChanged(ItemListener) you can track selecting and deselecting checkbox (and do whatever you want based on it):

myCheckBox.addItemListener(new ItemListener() {
    @Override
    public void itemStateChanged(ItemEvent e) {
        if(e.getStateChange() == ItemEvent.SELECTED) {//checkbox has been selected
            //do something...
        } else {//checkbox has been deselected
            //do something...
        };
    }
});

Java Swing itemStateChanged docu should help too. By using isSelected() method you can just test if actual is checkbox selected:

if(myCheckBox.isSelected()){_do_something_if_selected_}

I resolved issue using below steps :

1. Stop cassandara services

   sudo su -
   systemctl stop datastax-agent
   systemctl stop opscenterd
   systemctl stop app-dse
   

2. Take backup and Change port from 9042 to 9035

   cp /opt/dse/resources/cassandra/conf/cassandra.yaml /opt/dse/resources/cassandra/conf/bkp_cassandra.yaml
   Vi /opt/dse/resources/cassandra/conf/cassandra.yaml
   native_transport_port: 9035
   

3. Start Cassandra services

   systemctl start datastax-agent
   systemctl start opscenterd
   systemctl start app-dse
   

4. create cqlshrc file.

   vi  /root/.cassandra/cqlshrc
   
   [connection]
   hostname = 198.168.1.100
   port = 9035
   

Thanks, Mahesh

In Chrome when you load a website from some HTTP server both absolute paths (e.g. /images/sth.png) and relative paths to some upper level directory (e.g. ../images/sth.png) work.

But!

When you load (in Chrome!) a HTML document from local filesystem you cannot access directories above current directory. I.e. you cannot access ../something/something.sth and changing relative path to absolute or anything else won't help.

My impression is that your database is pretty enourmous or very badly designed if Linq2Sql does not fit your needs. I have around 10 websites both larger and smaller all using Linq2Sql. I have looked and Entity framework many times but I cannot find a good reason for using it over Linq2Sql. That said I try to use my databases as model so I already have a 1 to 1 mapping between model and database.

At my current job we have a database with 200+ tables. An old database with lots of bad solutions so there I could see the benefit of Entity Framework over Linq2Sql but still I would prefer to redesign the database since the database is the engine of the application and if the database is badly designed and slow then my application will also be slow. Using Entity framework on such a database seems like a quickfix to disguise the bad model but it could never disguise the bad performance you get from such a database.

You can use java.io.InputStream to read the file as shown below:

InputStream inputStream = getClass().getClassLoader().getResourceAsStream(myProps.properties); 

OK, this is a bad thing to be doing. Don't mock a list; instead, mock the individual objects inside the list. See Mockito: mocking an arraylist that will be looped in a for loop for how to do this.

Also, why are you using PowerMock? You don't seem to be doing anything that requires PowerMock.

But the real cause of your problem is that you are using when on two different objects, before you complete the stubbing. When you call when, and provide the method call that you are trying to stub, then the very next thing you do in either Mockito OR PowerMock is to specify what happens when that method is called - that is, to do the thenReturn part. Each call to when must be followed by one and only one call to thenReturn, before you do any more calls to when. You made two calls to when without calling thenReturn - that's your error.

I know this is an old question, but gracchus's solution doesn't work if file names contain spaces. VonC's solution to file names with spaces is to not remove them utilizing --ignore-unmatch, then remove them manually, but this will not work well if there are a lot.

Here is a solution that utilizes bash arrays to capture all files.

# Build bash array of the file names
while read -r file; do 
    rmlist+=( "$file" )
done < <(git ls-files -i --exclude-standard)

git rm –-cached "${rmlist[@]}"

git commit -m 'ignore update'

By default, IDLE has it on Shift-Left Bracket. However, if you want, you can customise it to be Shift-Tab by clicking Options --> Configure IDLE --> Keys --> Use a Custom Key Set --> dedent-region --> Get New Keys for Selection

Then you can choose whatever combination you want. (Don't forget to click apply otherwise all the settings would not get affected.)

Plug it into task scheduler, then turn off UAC.

The default location for logon scripts is the netlogon share of a domain controller. On the server this is located:

It can presumably be changes from this default but I've never met anyone that had a reason to.

<c-b>:resize-window -A

You probably want to have LI rather than the UL have the background-color:

.selected li {
  background-color: red;
}

Then you want to have a dynamic class for the UL:

<ul ng-repeat="vote in votes" ng-click="setSelected()" class="{{selected}}">

Now you need to update the $scope.selected when clicking the row:

$scope.setSelected = function() {
   console.log("show", arguments, this);
   this.selected = 'selected';
}

and then un-select the previously highlighted row:

$scope.setSelected = function() {
   // console.log("show", arguments, this);
   if ($scope.lastSelected) {
     $scope.lastSelected.selected = '';
   }
   this.selected = 'selected';
   $scope.lastSelected = this;
}

Answer from 2020 year :

dependencies {
    implementation "androidx.core:core-ktx:1.2.0"
}

and cal it simply in your code

view.updateLayoutParams<ViewGroup.MarginLayoutParams> {
   setMargins(5)
}

Another way of doing this, using only JavaScript, would be this:

window.addEventListener('resize', functionName);

This fires every time the size changes, like the other answer.

functionName is the name of the function being executed when the window is resized (the brackets on the end aren't necessary).

for Xamarin Android

Using command //get the file directory

Image image =new Image() { Source = file.Path };

then in command adb pull //the image file path here

As of March 2020, simply:

• Invite @RawDataBot to your group.

Upon joining it will output a JSON file where your chat id will be located at message.chat.id.

"message": {
    "chat": {
        "id": -210987654,
        "title": ...,
        "type": "group",
        ...
    }
    ...
}

Be sure to kick @RawDataBot from your group afterwards.

I used it and it run perfectly

<%=Request.QueryString["id"] %>

I was facing the same issue; and the following worked well for me. Hope this helps someone landing here:

<div class="row">
    <div class="col-md-6">
        <div class="col-md-12">
            Set room heater temperature
        </div>
    </div>
    <div class="col-md-6">
        <div class="col-md-12">
            Set room heater temperature
        </div>
    </div>
</div>

This will automatically render some space between the 2 divs.

check this Twig Reference.

You can do it that simple:

{% if (a or b) %}
    ...
{% endif %}

Send your data with SESSION rather than post.

session_start();
$_SESSION['foo'] = "bar";

On the page where you recieve the request, if you absolutely need POST data (some weird logic), you can do this somwhere at the beginning:

$_POST['foo'] = $_SESSION['foo'];

The post data will be valid just the same as if it was sent with POST.

Then destroy the session (or just unset the fields if you need the session for other purposes).

It is important to destroy a session or unset the fields, because unlike POST, SESSION will remain valid until you explicitely destroy it or until the end of browser session. If you don't do it, you can observe some strange results. For example: you use sesson for filtering some data. The user switches the filter on and gets filtered data. After a while, he returns to the page and expects the filter to be reset, but it's not: he still sees filtered data.

Here is how you can add an icon while creating an exe file from a Python file

• open command prompt at the place where Python file exist

• type:

  pyinstaller --onefile -i"path of icon"  path of python file
  

Example-

pyinstaller --onefile -i"C:\icon\Robot.ico" C:\Users\Jarvis.py

This is the easiest way to add an icon.

Another approach I would try is by using #map

clients.map{ |key, _| key if clients[key] == {"client_id"=>"2180"} }.compact 
#=> ["orange"]

This will return all occurences of given value. The underscore means that we don't need key's value to be carried around so that way it's not being assigned to a variable. The array will contain nils if the values doesn't match - that's why I put #compact at the end.

Just for the record:

>>> int('55063.000000')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: invalid literal for int() with base 10: '55063.000000'

Got me here...

>>> int(float('55063.000000'))
55063.0

Has to be used!

For Windows, via Console API:

void clear() {
    COORD topLeft  = { 0, 0 };
    HANDLE console = GetStdHandle(STD_OUTPUT_HANDLE);
    CONSOLE_SCREEN_BUFFER_INFO screen;
    DWORD written;

    GetConsoleScreenBufferInfo(console, &screen);
    FillConsoleOutputCharacterA(
        console, ' ', screen.dwSize.X * screen.dwSize.Y, topLeft, &written
    );
    FillConsoleOutputAttribute(
        console, FOREGROUND_GREEN | FOREGROUND_RED | FOREGROUND_BLUE,
        screen.dwSize.X * screen.dwSize.Y, topLeft, &written
    );
    SetConsoleCursorPosition(console, topLeft);
}

It happily ignores all possible errors, but hey, it's console clearing. Not like system("cls") handles errors any better.

For *nixes, you usually can go with ANSI escape codes, so it'd be:

void clear() {
    // CSI[2J clears screen, CSI[H moves the cursor to top-left corner
    std::cout << "\x1B[2J\x1B[H";
}

Using system for this is just ugly.

Since an ounce of experience is worth a ton of theory, I tried a little test program for MULTILINE:

#define MULTILINE(...) #__VA_ARGS__

const char *mstr[] =
{
    MULTILINE(1, 2, 3),       // "1, 2, 3"
    MULTILINE(1,2,3),         // "1,2,3"
    MULTILINE(1 , 2 , 3),     // "1 , 2 , 3"
    MULTILINE( 1 , 2 , 3 ),   // "1 , 2 , 3"
    MULTILINE((1,  2,  3)),   // "(1,  2,  3)"
    MULTILINE(1
              2
              3),             // "1 2 3"
    MULTILINE(1\n2\n3\n),     // "1\n2\n3\n"
    MULTILINE(1\n
              2\n
              3\n),           // "1\n 2\n 3\n"
    MULTILINE(1, "2" \3)      // "1, \"2\" \3"
};

Compile this fragment with cpp -P -std=c++11 filename to reproduce.

The trick behind #__VA_ARGS__ is that __VA_ARGS__ does not process the comma separator. So you can pass it to the stringizing operator. Leading and trailing spaces are trimmed, and spaces (including newlines) between words are compressed to a single space then. Parentheses need to be balanced. I think these shortcomings explain why the designers of C++11, despite #__VA_ARGS__, saw the need for raw string literals.

Please Set As Below

img = cv2.imread('2015-05-27-191152.jpg',1)     // Change Flag As 1 For Color Image
                                                //or O for Gray Image So It image is 
                                                //already gray

You can solve it with Joda Time:

Date utcDate = new Date(timezoneFrom.convertLocalToUTC(date.getTime(), false));
Date localDate = new Date(timezoneTo.convertUTCToLocal(utcDate.getTime()));

Java 8:

LocalDateTime localDateTime = LocalDateTime.parse("2007-12-03T10:15:30");
ZonedDateTime fromDateTime = localDateTime.atZone(
    ZoneId.of("America/Toronto"));
ZonedDateTime toDateTime = fromDateTime.withZoneSameInstant(
    ZoneId.of("Canada/Newfoundland"));

Just copy the part you want from the webpage and paste it in the wysiwyg editor. Check the html source by clicking on the "source" button on the editor toolbar.

I've found this most easiest way when I was working on a Drupal site. I use wysiwyg CKeditor.

C array:

NSInteger array[6] = {1, 2, 3, 4, 5, 6};

Objective-C Array:

NSArray *array = @[@1, @2, @3, @4, @5, @6];
// numeric values must in that case be wrapped into NSNumbers

Swift Array:

var array = [1, 2, 3, 4, 5, 6]

This is correct too:

var array = Array(1...10)

NB: arrays are strongly typed in Swift; in that case, the compiler infers from the content that the array is an array of integers. You could use this explicit-type syntax, too:

var array: [Int] = [1, 2, 3, 4, 5, 6]

If you wanted an array of Doubles, you would use :

var array = [1.0, 2.0, 3.0, 4.0, 5.0, 6.0] // implicit type-inference

or:

var array: [Double] = [1, 2, 3, 4, 5, 6] // explicit type

According to other answers I am adding the parallel stages scenario:

pipeline {
    agent any
    stages {
        stage('some parallel stage') {
            parallel {
                stage('parallel stage 1') {
                    when {
                      expression { ENV == "something" }
                    }
                    steps {
                        echo 'something'
                    }
                }
                stage('parallel stage 2') {
                    steps {
                        echo 'something'
                    }
                }
            }
        }
    }
}

I prefer Serializable = no boilerplate code. For passing data to other Fragments or Activities the speed difference to a Parcelable does not matter.

I would also always provide a helper method for a Fragment or Activity, this way you always know, what data has to be passed. Here an example for your ListMusicFragment:

private static final String EXTRA_MUSIC_LIST = "music_list";

public static ListMusicFragment createInstance(List<Music> music) {
    ListMusicFragment fragment = new ListMusicFragment();
    Bundle bundle = new Bundle();
    bundle.putSerializable(EXTRA_MUSIC_LIST, music);
    fragment.setArguments(bundle);
    return fragment;
}

@Override
public View onCreateView(...) { 
    ...
    Bundle bundle = intent.getArguments();
    List<Music> musicList = (List<Music>)bundle.getSerializable(EXTRA_MUSIC_LIST);
    ...
}

Random random = new Random();
double percent = 10.0; //10.0%
if (random.nextDouble() * 100D < percent) {
    //do
}

Probably the most definitive is Figure B.1(d) of the ggplot2 book, the appendices of which are available at http://ggplot2.org/book/appendices.pdf.

However, it is not quite that simple. hjust and vjust as described there are how it works in geom_text and theme_text (sometimes). One way to think of it is to think of a box around the text, and where the reference point is in relation to that box, in units relative to the size of the box (and thus different for texts of different size). An hjust of 0.5 and a vjust of 0.5 center the box on the reference point. Reducing hjust moves the box right by an amount of the box width times 0.5-hjust. Thus when hjust=0, the left edge of the box is at the reference point. Increasing hjust moves the box left by an amount of the box width times hjust-0.5. When hjust=1, the box is moved half a box width left from centered, which puts the right edge on the reference point. If hjust=2, the right edge of the box is a box width left of the reference point (center is 2-0.5=1.5 box widths left of the reference point. For vertical, less is up and more is down. This is effectively what that Figure B.1(d) says, but it extrapolates beyond [0,1].

But, sometimes this doesn't work. For example

DF <- data.frame(x=c("a","b","cdefghijk","l"),y=1:4)
p <- ggplot(DF, aes(x,y)) + geom_point()

p + opts(axis.text.x=theme_text(vjust=0))
p + opts(axis.text.x=theme_text(vjust=1))
p + opts(axis.text.x=theme_text(vjust=2))

The three latter plots are identical. I don't know why that is. Also, if text is rotated, then it is more complicated. Consider

p + opts(axis.text.x=theme_text(hjust=0, angle=90))
p + opts(axis.text.x=theme_text(hjust=0.5 angle=90))
p + opts(axis.text.x=theme_text(hjust=1, angle=90))
p + opts(axis.text.x=theme_text(hjust=2, angle=90))

The first has the labels left justified (against the bottom), the second has them centered in some box so their centers line up, and the third has them right justified (so their right sides line up next to the axis). The last one, well, I can't explain in a coherent way. It has something to do with the size of the text, the size of the widest text, and I'm not sure what else.

   # Try it as UTF-8 directly

What the error is telling, is that you can't convert an entire list into an integer. You could get an index from the list and convert that into an integer:

x = ["0", "1", "2"] 
y = int(x[0]) #accessing the zeroth element

If you're trying to convert a whole list into an integer, you are going to have to convert the list into a string first:

x = ["0", "1", "2"]
y = ''.join(x) # converting list into string
z = int(y)

If your list elements are not strings, you'll have to convert them to strings before using str.join:

x = [0, 1, 2]
y = ''.join(map(str, x))
z = int(y)

Also, as stated above, make sure that you're not returning a nested list.

Written a simplest extension that works for us. If anyone looks for it...

public static class DateTimeExtensions
{
    public static DateTime FromUnixTimeStampToDateTime(this string unixTimeStamp)
    {

        return DateTimeOffset.FromUnixTimeSeconds(long.Parse(unixTimeStamp)).UtcDateTime;
    }
}

Having tried the css route for a while, I ended up writing something fairly basic in jQuery that did the job for me:

function iframeHeight() {
    var newHeight = $j(window).height();
    var buffer = 180;     // space required for any other elements on the page 
    var newIframeHeight = newHeight - buffer;
    $j('iframe').css('height',newIframeHeight);    //this will aply to all iframes on the page, so you may want to make your jquery selector more specific.
}

// When DOM ready
$(function() {
    window.onresize = iframeHeight;
}

Tested in IE8, Chrome, Firefox 3.6

think the check you're looking for is this:

if(Request.QueryString["query"] != null) 

It returns null because in that query string it has no value for that key.

if you are using extracted tomcat then,

startup.sh and shutdown.sh are two script located in TOMCAT/bin/ to start and shutdown tomcat, You could use that

if tomcat is installed then

/etc/init.d/tomcat5.5 start
/etc/init.d/tomcat5.5 stop
/etc/init.d/tomcat5.5 restart

Maybe you defined one provider like <provider>org.hibernate.ejb.HibernatePersistence</provider> but referencing another one in jar. That happened with me: my persistence.xml provider was openjpa but I was using eclipselink in my classpath. Hope this help!

I will do like....

(!DBNull.Value.Equals(dataSet.Tables[6].Rows[0]["_id"]))

The git command that would be the closest from what you are looking for would by git archive.
See backing up project which uses git: it will include in an archive all files (including submodules if you are using the git-archive-all script)

You can then use that archive anywhere, giving you back only files, no .git directory.

git archive --remote=<repository URL> | tar -t

If you need folders and files just from the first level:

git archive --remote=<repository URL> | tar -t --exclude="*/*"

To list only first-level folders of a remote repo:

git archive --remote=<repository URL> | tar -t --exclude="*/*" | grep "/"

Note: that does not work for GitHub (not supported)

So you would need to clone (shallow to quicken the clone step), and then archive locally:

git clone --depth=1 [email protected]:xxx/yyy.git
cd yyy
git archive --format=tar aTag -o aTag.tar

Another option would be to do a shallow clone (as mentioned below), but locating the .git folder elsewhere.

git --git-dir=/path/to/another/folder.git clone --depth=1 /url/to/repo

The repo folder would include only the file, without .git.

Note: git --git-dir is an option of the command git, not git clone.

Update with Git 2.14.X/2.15 (Q4 2017): it will make sure to avoid adding empty folders.

"git archive", especially when used with pathspec, stored an empty directory in its output, even though Git itself never does so.
This has been fixed.

See commit 4318094 (12 Sep 2017) by René Scharfe (``).
Suggested-by: Jeff King (peff).
^{(Merged by Junio C Hamano -- gitster -- in commit 62b1cb7, 25 Sep 2017)}

archive: don't add empty directories to archives

While git doesn't track empty directories, git archive can be tricked into putting some into archives.
While that is supported by the object database, it can't be represented in the index and thus it's unlikely to occur in the wild.

As empty directories are not supported by git, they should also not be written into archives.
If an empty directory is really needed then it can be tracked and archived by placing an empty .gitignore file in it.

If you patch /Developer/Platforms/iPhoneOS.platform/Info.plist and then try to debug a application running on the device using a real development provisionen profile from Apple it will probably not work. Symptoms are weird error messages from com.apple.debugserver and that you can use any bundle identifier without getting a error when building in Xcode. The solution is to restore Info.plist.

For me it was the

in the page source.

Congratulations, you've hit my favorite pet peeve with JDBC: Date class handling.

Basically databases usually support at least three forms of datetime fields which are date, time and timestamp. Each of these have a corresponding class in JDBC and each of them extend java.util.Date. Quick semantics of each of these three are the following:

• java.sql.Date corresponds to SQL DATE which means it stores years, months and days while hour, minute, second and millisecond are ignored. Additionally sql.Date isn't tied to timezones.
• java.sql.Time corresponds to SQL TIME and as should be obvious, only contains information about hour, minutes, seconds and milliseconds.
• java.sql.Timestamp corresponds to SQL TIMESTAMP which is exact date to the nanosecond (note that util.Date only supports milliseconds!) with customizable precision.

One of the most common bugs when using JDBC drivers in relation to these three types is that the types are handled incorrectly. This means that sql.Date is timezone specific, sql.Time contains current year, month and day et cetera et cetera.

Finally: Which one to use?

Depends on the SQL type of the field, really. PreparedStatement has setters for all three values, #setDate() being the one for sql.Date, #setTime() for sql.Time and #setTimestamp() for sql.Timestamp.

Do note that if you use ps.setObject(fieldIndex, utilDateObject); you can actually give a normal util.Date to most JDBC drivers which will happily devour it as if it was of the correct type but when you request the data afterwards, you may notice that you're actually missing stuff.

I'm really saying that none of the Dates should be used at all.

What I am saying that save the milliseconds/nanoseconds as plain longs and convert them to whatever objects you are using (obligatory joda-time plug). One hacky way which can be done is to store the date component as one long and time component as another, for example right now would be 20100221 and 154536123. These magic numbers can be used in SQL queries and will be portable from database to another and will let you avoid this part of JDBC/Java Date API:s entirely.

you can use success function, once see this jquery.ajax settings

 $('#ChangePermission').click(function(){
    $.ajax({
        url: 'change_permission.php',
        type: 'POST',
        data: {
        'user': document.GetElementById("user").value,
        'perm': document.GetElementById("perm").value
        }
       success:function(result)//we got the response
       {
        //you can try to write alert(result) to see what is the response,this result variable will contains what you prints in the php page
       }
    })
})

we can also have error() function

hope this helps you

UPDATE:

Time has changed, you can now remove (expire) TestFlight Builds as in this answer but you still cannot delete the build.

OLD:

I asked apple and here is their answer:

I understand you would like to remove a build from iTunes Connect as shown in your screenshot.

Please be advised this is expected behavior as you can remove a build from being the current build but you cannot delete it from iTunes Connect. For more information, please refer to the iTunes Connect Developer Guide: https://developer.apple.com/library/content/documentation/LanguagesUtilities/Conceptual/iTunesConnect_Guide/

So i just can't.

You can use this command:

I am using Pillow 4.1.1 (the successor of PIL) in Python 3.5. The conversion between Pillow and numpy is straightforward.

from PIL import Image
import numpy as np
im = Image.open('1.jpg')
im2arr = np.array(im) # im2arr.shape: height x width x channel
arr2im = Image.fromarray(im2arr)

One thing that needs noticing is that Pillow-style im is column-major while numpy-style im2arr is row-major. However, the function Image.fromarray already takes this into consideration. That is, arr2im.size == im.size and arr2im.mode == im.mode in the above example.

We should take care of the HxWxC data format when processing the transformed numpy arrays, e.g. do the transform im2arr = np.rollaxis(im2arr, 2, 0) or im2arr = np.transpose(im2arr, (2, 0, 1)) into CxHxW format.

I know this was answered a long time ago, but I've recently spent hours trying to solve a similar problem. The setup is local PC running Debian 8 using Eclipse CDT Neon.2, remote ARM7 board (Olimex) running Debian 7. Tool chain is Linaro 4.9 using gdbserver on the remote board and the Linaro GDB on the local PC. My issue was that the debug session would start and the program would execute, but breakpoints did not work and when manually paused "no source could be found" would result. My compile line options (Linaro gcc) included -ggdb -O0 as many have suggested but still the same problem. Ultimately I tried gdb proper on the remote board and it complained of no symbols. The curious thing was that 'file' reported debug not stripped on the target executable.

I ultimately solved the problem by adding -g to the linker options. I won't claim to fully understand why this helped, but I wanted to pass this on for others just in case it helps. In this case Linux did indeed need -g on the linker options.

You have to retrieve it from the HOST header.

var host = req.get('host');

It is optional with HTTP 1.0, but required by 1.1. And, the app can always impose a requirement of its own.

If this is for supporting cross-origin requests, you would instead use the Origin header.

var origin = req.get('origin');

Note that some cross-origin requests require validation through a "preflight" request:

req.options('/route', function (req, res) {
    var origin = req.get('origin');
    // ...
});

If you're looking for the client's IP, you can retrieve that with:

var userIP = req.socket.remoteAddress;

• message.socket.
• socket.remoteAddress

Note that, if your server is behind a proxy, this will likely give you the proxy's IP. Whether you can get the user's IP depends on what info the proxy passes along. But, it'll typically be in the headers as well.

Call visudo and add this:

user1 ALL=(user2) NOPASSWD: /home/user2/bin/test.sh

The command paths must be absolute! Then call sudo -u user2 /home/user2/bin/test.sh from a user1 shell. Done.

Ben Alman has a great jQuery plugin for dealing with this: http://benalman.com/projects/jquery-hashchange-plugin/

If you're not using jQuery it may be an interesting reference to dissect.

These solutions are pretty good, but they are forgetting that there may be other status codes than 200 OK. This is a solution that I've used on production environments for status monitoring and such.

If there is a url redirect or some other condition on the target page, the return will be true using this method. Also, GetResponse() will throw an exception and hence you will not get a StatusCode for it. You need to trap the exception and check for a ProtocolError.

Any 400 or 500 status code will return false. All others return true. This code is easily modified to suit your needs for specific status codes.

/// <summary>
/// This method will check a url to see that it does not return server or protocol errors
/// </summary>
/// <param name="url">The path to check</param>
/// <returns></returns>
public bool UrlIsValid(string url)
{
    try
    {
        HttpWebRequest request = HttpWebRequest.Create(url) as HttpWebRequest;
        request.Timeout = 5000; //set the timeout to 5 seconds to keep the user from waiting too long for the page to load
        request.Method = "HEAD"; //Get only the header information -- no need to download any content

        using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
        {
            int statusCode = (int)response.StatusCode;
            if (statusCode >= 100 && statusCode < 400) //Good requests
            {
                return true;
            }
            else if (statusCode >= 500 && statusCode <= 510) //Server Errors
            {
                //log.Warn(String.Format("The remote server has thrown an internal error. Url is not valid: {0}", url));
                Debug.WriteLine(String.Format("The remote server has thrown an internal error. Url is not valid: {0}", url));
                return false;
            }
        }
    }
    catch (WebException ex)
    {
        if (ex.Status == WebExceptionStatus.ProtocolError) //400 errors
        {
            return false;
        }
        else
        {
            log.Warn(String.Format("Unhandled status [{0}] returned for url: {1}", ex.Status, url), ex);
        }
    }
    catch (Exception ex)
    {
        log.Error(String.Format("Could not test url {0}.", url), ex);
    }
    return false;
}

If what you are trying to do is to split a string into several lines, you can use a backslash:

$ a="hello\
> world"
$ echo $a
helloworld

With one space in between:

$ a="hello \
> world"
$ echo $a
hello world

This one also adds only one space in between:

$ a="hello \
>      world"
$ echo $a
hello world

Simply alter your table, no need to any thing. just run this query on database. ALTER TABLE table_nameCONVERT TO CHARACTER SET utf8

it will definately work.

Assuming you're the administrator of the machine, Ubuntu has granted you the right to sudo to run any command as any user.
Also assuming you did not restrict the rights in the pg_hba.conf file (in the /etc/postgresql/9.1/main directory), it should contain this line as the first rule:

# Database administrative login by Unix domain socket  
local   all             postgres                                peer

(About the file location: 9.1 is the major postgres version and main the name of your "cluster". It will differ if using a newer version of postgres or non-default names. Use the pg_lsclusters command to obtain this information for your version/system).

Anyway, if the pg_hba.conf file does not have that line, edit the file, add it, and reload the service with sudo service postgresql reload.

Then you should be able to log in with psql as the postgres superuser with this shell command:

sudo -u postgres psql

Once inside psql, issue the SQL command:

ALTER USER postgres PASSWORD 'newpassword';

In this command, postgres is the name of a superuser. If the user whose password is forgotten was ritesh, the command would be:

ALTER USER ritesh PASSWORD 'newpassword';

References: PostgreSQL 9.1.13 Documentation, Chapter 19. Client Authentication

Keep in mind that you need to type postgres with a single S at the end

If leaving the password in clear text in the history of commands or the server log is a problem, psql provides an interactive meta-command to avoid that, as an alternative to ALTER USER ... PASSWORD:

\password username

It asks for the password with a double blind input, then hashes it according to the password_encryption setting and issue the ALTER USER command to the server with the hashed version of the password, instead of the clear text version.

Try [UIFont systemFontOfSize:36] or [UIFont fontWithName:@"HelveticaNeue" size:36] i.e. [[self titleLabel] setFont:[UIFont systemFontOfSize:36]];

As an extension to Ignacio Vazquez-Abrams' answer

>>> u'a?ä'.encode('ascii', 'ignore')
'a'

It is sometimes desirable to remove accents from characters and print the base form. This can be accomplished with

>>> import unicodedata
>>> unicodedata.normalize('NFKD', u'a?ä').encode('ascii', 'ignore')
'aa'

You may also want to translate other characters (such as punctuation) to their nearest equivalents, for instance the RIGHT SINGLE QUOTATION MARK unicode character does not get converted to an ascii APOSTROPHE when encoding.

>>> print u'\u2019'
’
>>> unicodedata.name(u'\u2019')
'RIGHT SINGLE QUOTATION MARK'
>>> u'\u2019'.encode('ascii', 'ignore')
''
# Note we get an empty string back
>>> u'\u2019'.replace(u'\u2019', u'\'').encode('ascii', 'ignore')
"'"

Although there are more efficient ways to accomplish this. See this question for more details Where is Python's "best ASCII for this Unicode" database?

Just call the modal method(without passing any parameters) using jQuery selector.

Here is example:

$('#modal').modal();

function getURLParameters(paramName) 
{
        var sURL = window.document.URL.toString();  
    if (sURL.indexOf("?") > 0)
    {
       var arrParams = sURL.split("?");         
       var arrURLParams = arrParams[1].split("&");      
       var arrParamNames = new Array(arrURLParams.length);
       var arrParamValues = new Array(arrURLParams.length);     
       var i = 0;
       for (i=0;i<arrURLParams.length;i++)
       {
        var sParam =  arrURLParams[i].split("=");
        arrParamNames[i] = sParam[0];
        if (sParam[1] != "")
            arrParamValues[i] = unescape(sParam[1]);
        else
            arrParamValues[i] = "No Value";
       }

       for (i=0;i<arrURLParams.length;i++)
       {
                if(arrParamNames[i] == paramName){
            //alert("Param:"+arrParamValues[i]);
                return arrParamValues[i];
             }
       }
       return "No Parameters Found";
    }

}

I'd like to add that TypeGuards only work on strings or numbers, if you want to compare an object use instanceof

if(task.id instanceof UUID) {
  //foo
}

cbindX from the package gdata combines multiple columns of differing column and row lengths. Check out the page here:

http://hosho.ees.hokudai.ac.jp/~kubo/Rdoc/library/gdata/html/cbindX.html

It takes multiple comma separated matrices and data.frames as input :) You just need to

install.packages("gdata", dependencies=TRUE)

and then

library(gdata)
concat_data <- cbindX(df1, df2, df3) # or cbindX(matrix1, matrix2, matrix3, matrix4)

You can add an auto generated id field in the table and select by this id

SELECT * FROM CUSTOMER WHERE CUSTOMER_ID = 3;

You can use a web-service from http://ip-api.com
in your php code, do as follow :

<?php
$ip = $_REQUEST['REMOTE_ADDR']; // the IP address to query
$query = @unserialize(file_get_contents('http://ip-api.com/php/'.$ip));
if($query && $query['status'] == 'success') {
  echo 'Hello visitor from '.$query['country'].', '.$query['city'].'!';
} else {
  echo 'Unable to get location';
}
?>

the query have many other informations:

array (
  'status'      => 'success',
  'country'     => 'COUNTRY',
  'countryCode' => 'COUNTRY CODE',
  'region'      => 'REGION CODE',
  'regionName'  => 'REGION NAME',
  'city'        => 'CITY',
  'zip'         => ZIP CODE,
  'lat'         => LATITUDE,
  'lon'         => LONGITUDE,
  'timezone'    => 'TIME ZONE',
  'isp'         => 'ISP NAME',
  'org'         => 'ORGANIZATION NAME',
  'as'          => 'AS NUMBER / NAME',
  'query'       => 'IP ADDRESS USED FOR QUERY',
)

CultureInfo.CurrentCulture.DateTimeFormat.GetMonthName(1);

See Here for more details.

Or

DateTime dt = DateTime.Now;
Console.WriteLine( dt.ToString( "MMMM" ) );

Or if you want to get the culture-specific abbreviated name.

GetAbbreviatedMonthName(1);

I'm agree with Spence (+1), but if you're doing it for learning or testing pourposes, you can use a foreach in the string, appending each char to the securestring using the AppendChar method.

_{I guess many people are entering in this question looking for a way to avoid the new line in awk. Thus, I am going to offer a solution to just that, since the answer to the specific context was already solved!}

In awk, print automatically inserts a ORS after printing. ORS stands for "output record separator" and defaults to the new line. So whenever you say print "hi" awk prints "hi" + new line.

This can be changed in two different ways: using an empty ORS or using printf.

Using an empty ORS

awk -v ORS= '1' <<< "hello
man"

This returns "helloman", all together.

The problem here is that not all awks accept setting an empty ORS, so you probably have to set another record separator.

awk -v ORS="-" '{print ...}' file

For example:

awk -v ORS="-" '1' <<< "hello
man"

Returns "hello-man-".

Using printf (preferable)

While print attaches ORS after the record, printf does not. Thus, printf "hello" just prints "hello", nothing else.

$ awk 'BEGIN{print "hello"; print "bye"}'
hello
bye
$ awk 'BEGIN{printf "hello"; printf "bye"}'
hellobye

Finally, note that in general this misses a final new line, so that the shell prompt will be in the same line as the last line of the output. To clean this, use END {print ""} so a new line will be printed after all the processing.

$ seq 5 | awk '{printf "%s", $0}'
12345$
#    ^ prompt here

$ seq 5 | awk '{printf "%s", $0} END {print ""}'
12345

Create a new sub with the following code and assign it to your button. Change the "DeleteProcess" to the name of your code to do the deletion. This will pop up a box with OK or Cancel and will call your delete sub if you hit ok and not if you hit cancel.

Sub AreYouSure()

Dim Sure As Integer

Sure = MsgBox("Are you sure?", vbOKCancel)
If Sure = 1 Then Call DeleteProcess

In SQL Server 2016 the wizard is a separate app. (Important: Excel wizard is only available in the 32-bit version of the wizard!). Use the MSDN page for instructions:

On the Start menu, point to All Programs, point toMicrosoft SQL Server , and then click Import and Export Data.
—or—
In SQL Server Data Tools (SSDT), right-click the SSIS Packages folder, and then click SSIS Import and Export Wizard.
—or—
In SQL Server Data Tools (SSDT), on the Project menu, click SSIS Import and Export Wizard.
—or—
In SQL Server Management Studio, connect to the Database Engine server type, expand Databases, right-click a database, point to Tasks, and then click Import Data or Export data.
—or—
In a command prompt window, run DTSWizard.exe, located in C:\Program Files\Microsoft SQL Server\100\DTS\Binn.

After that it should be pretty much the same (possibly with minor variations in the UI) as in @marc_s's answer.

Update the master branch, which you need to do regardless.

Then, one of:

1. Rebase the old branch against the master branch. Solve the merge conflicts during rebase, and the result will be an up-to-date branch that merges cleanly against master.

2. Merge your branch into master, and resolve the merge conflicts.

3. Merge master into your branch, and resolve the merge conflicts. Then, merging from your branch into master should be clean.

None of these is better than the other, they just have different trade-off patterns.

I would use the rebase approach, which gives cleaner overall results to later readers, in my opinion, but that is nothing aside from personal taste.

To rebase and keep the branch you would:

git checkout <branch> && git rebase <target>

In your case, check out the old branch, then

git rebase master 

to get it rebuilt against master.

Inside for-loops and iterator methods like each and map the next keyword in ruby will have the effect of jumping to the next iteration of the loop (same as continue in C).

However what it actually does is just to return from the current block. So you can use it with any method that takes a block - even if it has nothing to do with iteration.

Check my solution, It will work.

Solutions:

First Download Subversion 1.8.13 ( 1.8 ) Download link ( https://www.visualsvn.com/downloads/ )

Then unzipped in a folder. There will have one folder "bin".

Then

Go to settings - > Version control -> Subversion

Copy the url of your downloaded svn.exe that is in bin folder that you have downloaded.

follow the pic:

Don't forget to give the end name like svn.exe last as per image.

Apply -> Ok

Restart your android studio now.

Happy Coding!

Set content-type and other headers before you write the file out. For small files the content is buffered, and the browser gets the headers first. For big ones the data come first.

iterating over Ihab's answer, just using position:fixed and bootstraps col-offset you don't need to be specific on the width.

I have been using jQuery and calling a function to populate drop downs.

function loadDropDowns(name,value)
{
   var ddl = "#Categories";
   $(ddl).append('<option value="' + value + '">' + name + "</option>'");
}

This answer seems to be the answer you are looking for Why can't I do this: dynamic x = new ExpandoObject { Foo = 12, Bar = "twelve" }

Read about the ExpandoObject here https://msdn.microsoft.com/en-us/library/system.dynamic.expandoobject(v=vs.110).aspx

And the dynamic type here https://msdn.microsoft.com/en-GB/library/dd264736.aspx

Today you can select elements with the same id attribute this way:

document.querySelectorAll('[id=test]');

Or this way with jQuery:

$('[id=test]');

CSS selector #test { ... } should work also for all elements with id = "test". ?ut the only thing: document.querySelectorAll('#test') (or $('#test') ) - will return only a first element with this id. Is it good, or not - I can't tell . But sometimes it is difficult to follow unique id standart .

For example you have the comment widget, with HTML-ids, and JS-code, working with these HTML-ids. Sooner or later you'll need to render this widget many times, to comment a different objects into a single page: and here the standart will broken (often there is no time or not allow - to rewrite built-in code).

You can check Announcing the official release of the Visual C++ Build Tools 2015 and from this blog, we can know that the Build Tools are the same C++ tools that you get with Visual Studio 2015 but they come in a scriptable standalone installer that only lays down the tools you need to build C++ projects. The Build Tools give you a way to install the tools you need on your build machines without the IDE you don’t need.

Because these components are the same as the ones installed by the Visual Studio 2015 Update 2 setup, you cannot install the Visual C++ Build Tools on a machine that already has Visual Studio 2015 installed. Therefore, it asks you to uninstall your existing VS 2015 when you tried to install the Visual C++ build tools using the standalone installer. Since you already have the VS 2015, you can go to Control Panel—Programs and Features and right click the VS 2015 item and Change-Modify, then check the option of those components that relates to the Visual C++ Build Tools, like Visual C++, Windows SDK… then install them. After the installation is successful, you can build the C++ projects.

If you want to use Unix shell commands on Windows, you can use Windows Powershell, which includes both Windows and Unix commands as aliases. You can find more info on it in the documentation.

PowerShell supports aliases to refer to commands by alternate names. Aliasing allows users with experience in other shells to use common command names that they already know for similar operations in PowerShell.

The PowerShell equivalents may not produce identical results. However, the results are close enough that users can do work without knowing the PowerShell command name.

find_elements_by_xpath("//*[@class='class name']")

is a great solution

I would recommend you using the Conditional Attribute!

Update: 3.5 years later

You can use #if like this (example copied from MSDN):

// preprocessor_if.cs
#define DEBUG
#define VC_V7
using System;
public class MyClass 
{
    static void Main() 
    {
#if (DEBUG && !VC_V7)
        Console.WriteLine("DEBUG is defined");
#elif (!DEBUG && VC_V7)
        Console.WriteLine("VC_V7 is defined");
#elif (DEBUG && VC_V7)
        Console.WriteLine("DEBUG and VC_V7 are defined");
#else
        Console.WriteLine("DEBUG and VC_V7 are not defined");
#endif
    }
}

Only useful for excluding parts of methods.

If you use #if to exclude some method from compilation then you will have to exclude from compilation all pieces of code which call that method as well (sometimes you may load some classes at runtime and you cannot find the caller with "Find all references"). Otherwise there will be errors.

If you use conditional compilation on the other hand you can still leave all pieces of code that call the method. All parameters will still be validated by the compiler. The method just won't be called at runtime. I think that it is way better to hide the method just once and not have to remove all the code that calls it as well. You are not allowed to use the conditional attribute on methods which return value - only on void methods. But I don't think this is a big limitation because if you use #if with a method that returns a value you have to hide all pieces of code that call it too.

Here is an example:

    // calling Class1.ConditionalMethod() will be ignored at runtime 
    // unless the DEBUG constant is defined


    using System.Diagnostics;
    class Class1 
    {
       [Conditional("DEBUG")]
       public static void ConditionalMethod() {
          Console.WriteLine("Executed Class1.ConditionalMethod");
       }
    }

Summary:

I would use #ifdef in C++ but with C#/VB I would use Conditional attribute. This way you hide the method definition without having to hide the pieces of code that call it. The calling code is still compiled and validated by the compiler, the method is not called at runtime though. You may want to use #if to avoid dependencies because with Conditional attribute your code is still compiled.

You can use

filter: brightness(0) invert(1);

First, brightness(0) makes all image black, except transparent parts, which remain transparent.

Then, invert(1) makes the black parts white.

Firstly, application.properties in the @PropertySource should read application-test.properties if that's what the file is named (matching these things up matters):

@PropertySource("classpath:application-test.properties ")

That file should be under your /src/test/resources classpath (at the root).

I don't understand why you'd specify a dependency hard coded to a file called application-test.properties. Is that component only to be used in the test environment?

The normal thing to do is to have property files with the same name on different classpaths. You load one or the other depending on whether you are running your tests or not.

In a typically laid out application, you'd have:

src/test/resources/application.properties

and

src/main/resources/application.properties

And then inject it like this:

@PropertySource("classpath:application.properties")

The even better thing to do would be to expose that property file as a bean in your spring context and then inject that bean into any component that needs it. This way your code is not littered with references to application.properties and you can use anything you want as a source of properties. Here's an example: how to read properties file in spring project?

PAGEIOLATCH_SH wait type usually comes up as the result of fragmented or unoptimized index.

Often reasons for excessive PAGEIOLATCH_SH wait type are:

• I/O subsystem has a problem or is misconfigured
• Overloaded I/O subsystem by other processes that are producing the high I/O activity
• Bad index management
• Logical or physical drive misconception
• Network issues/latency
• Memory pressure
• Synchronous Mirroring and AlwaysOn AG

In order to try and resolve having high PAGEIOLATCH_SH wait type, you can check:

• SQL Server, queries and indexes, as very often this could be found as a root cause of the excessive PAGEIOLATCH_SH wait types
• For memory pressure before jumping into any I/O subsystem troubleshooting

Always keep in mind that in case of high safety Mirroring or synchronous-commit availability in AlwaysOn AG, increased/excessive PAGEIOLATCH_SH can be expected.

You can find more details about this topic in the article Handling excessive SQL Server PAGEIOLATCH_SH wait types

Opposite up is children(), but opposite in position is prepend(). Here a very good tutorial.

Throwing an exception will be good especially if you want to clarify the error reason:

throw "Error Message"

This will generate a terminating error.

Another case that this might be happening is if your data was improperly written to your csv to have each row end with a comma. This will leave you with an unnamed column Unnamed: x at the end of your data when you try to read it into a df.

just go into XML file and give id to your webView then in java paste these line:

If you are trying to keep a list of lists (similar to python's list.append()) then this might work:

• Click ? Tools on the toolbar, to the right of the tabs.
• Select Developer Tools. The Developer Tools dialogue should open.
• Click the Script tab in the dialogue.
• Click the Start Debugging button.

You can use watch, breakpoint, see the call stack etc, similarly to debuggers in professional browsers.

You can also use the statement debugger; in your JavaScript code the set a breakpoint.

Per documentation, android:weightSum defines the maximum weight sum, and is calculated as the sum of the layout_weight of all the children if not specified explicitly.

Let's consider an example with a LinearLayout with horizontal orientation and 3 ImageViews inside it. Now we want these ImageViews always to take equal space. To acheive this, you can set the layout_weight of each ImageView to 1 and the weightSum will be calculated to be equal to 3 as shown in the comment.

<LinearLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    <!-- android:weightSum="3" -->

weightSum is useful for having the layout rendered correctly for any device, which will not happen if you set width and height directly.

There is one tiny difference in Swift 3.0 and Xcode8

Whenever you want to apply corner radius to UIView, make sure you call yourUIView.layoutIfNeeded() before calling cornerRadius.

Otherwise, it will return the default value for UIView's height and width (1000.0) which will probably make your View disappear.

Always make sure that all effects that changes the size of UIView (Interface builder constraints etc) are applied before setting any layer properties.

Example of UIView class implementation

class BadgeView: UIView {

  override func awakeFromNib() {

    self.layoutIfNeeded()
    layer.cornerRadius = self.frame.height / 2.0
    layer.masksToBounds = true

   }
 }

DateFormatter has some factory date styles for those too lazy to tinker with formatting strings. If you don't need a custom style, here's another option:

extension Date {  
  func asString(style: DateFormatter.Style) -> String {
    let dateFormatter = DateFormatter()
    dateFormatter.dateStyle = style
    return dateFormatter.string(from: self)
  }
}

This gives you the following styles:

short, medium, long, full

Example usage:

let myDate = Date()
myDate.asString(style: .full)   // Wednesday, January 10, 2018
myDate.asString(style: .long)   // January 10, 2018
myDate.asString(style: .medium) // Jan 10, 2018
myDate.asString(style: .short)  // 1/10/18

I had the same issue, in my case the following was missing from my xxx-servlet.xml config file

<mvc:annotation-driven/>

As soon I added this it it worked.

This answer presents a hack, but I would highly recommend you to use flexbox (as stated in @Haschem answer), since it's now supported everywhere.

Demos link:
- Bootstrap 3
- Bootstrap 4 alpha 6

You still can use a custom class when you need it:

.vcenter {_x000D_
    display: inline-block;_x000D_
    vertical-align: middle;_x000D_
    float: none;_x000D_
}

<div class="row">_x000D_
    <div class="col-xs-5 col-md-3 col-lg-1 vcenter">_x000D_
        <div style="height:10em;border:1px solid #000">Big</div>_x000D_
    </div><!--_x000D_
    --><div class="col-xs-5 col-md-7 col-lg-9 vcenter">_x000D_
        <div style="height:3em;border:1px solid #F00">Small</div>_x000D_
    </div>_x000D_
</div>

Bootply

Using inline-block adds extra space between blocks if you let a real space in your code (like ...</div> </div>...). This extra space breaks our grid if column sizes add up to 12:

<div class="row">
    <div class="col-xs-6 col-md-4 col-lg-2 vcenter">
        <div style="height:10em;border:1px solid #000">Big</div>
    </div>
    <div class="col-xs-6 col-md-8 col-lg-10 vcenter">
        <div style="height:3em;border:1px solid #F00">Small</div>
    </div>
</div>

Here, we've got extra spaces between <div class="[...] col-lg-2"> and <div class="[...] col-lg-10"> (a carriage return and 2 tabs/8 spaces). And so...

Let's kick this extra space!!

<div class="row">
    <div class="col-xs-6 col-md-4 col-lg-2 vcenter">
        <div style="height:10em;border:1px solid #000">Big</div>
    </div><!--
    --><div class="col-xs-6 col-md-8 col-lg-10 vcenter">
        <div style="height:3em;border:1px solid #F00">Small</div>
    </div>
</div>

Notice the seemingly useless comments <!-- ... -->? They are important -- without them, the whitespace between the <div> elements will take up space in the layout, breaking the grid system.

Note: the Bootply has been updated

I spent some time on this very problem - I was trying to verify a file existed before opening it.

Eventually, I came up with a solution using XML and SOAP - use the EnumerateFolder method and pull in an XML response with the folder's contents.

I blogged about it here.

You can do that with list-style-position: inside; on the ul element :

ul {
    list-style-position: inside;
}

See working fiddle

Just for convenience:

template<class V, typename T>
bool in(const V &v, const T &el) {
    return std::find(v.begin(), v.end(), el) != v.end();
}

The actual splitting based on multiple delimiters:

std::vector<std::string> split(const std::string &s,
                               const std::vector<char> &delims) {
    std::vector<std::string> res;
    auto stuff = [&delims](char c) { return !in(delims, c); };
    auto space = [&delims](char c) { return in(delims, c); };
    auto first = std::find_if(s.begin(), s.end(), stuff);
    while (first != s.end()) {
        auto last = std::find_if(first, s.end(), space);
        res.push_back(std::string(first, last));
        first = std::find_if(last + 1, s.end(), stuff);
    }
    return res;
}

The usage:

int main() {
    std::string s = "   aaa,  bb  cc ";
    for (auto el: split(s, {' ', ','}))
        std::cout << el << std::endl;
    return 0;
}

The following will be able to process very large files quickly.

$file = New-Object System.IO.StreamReader -Arg "file1.txt"
$outstream = [System.IO.StreamWriter] "file2.txt"
$count = 0 

while ($line = $file.ReadLine()) {
      $count += 1
      $s = $line -replace "`n", "`r`n"
      $outstream.WriteLine($s)
  }

$file.close()
$outstream.close()

Write-Host ([string] $count + ' lines have been processed.')

I used below method, which doesn't require any change in config, tested on mysql-5.5.51-winx64 and 5.5.50-MariaDB:

put 'load data...' in .sql file (ex: LoadTableName.sql)

LOAD DATA INFILE 'D:\\Work\\TableRecords.csv' INTO TABLE tbl1 FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '\r\n' IGNORE 1 LINES (col1,col2);

then:

mysql -uroot -pStr0ngP@ss -Ddatabasename -e "source D:\Work\LoadTableName.sql"

How can I check to see if a database in SQL Server is case-sensitive?

You can use below query that returns your informed database is case sensitive or not or is in binary sort(with null result):

;WITH collations AS (
    SELECT 
        name,
        CASE 
            WHEN description like '%case-insensitive%' THEN 0 
            WHEN description like '%case-sensitive%' THEN 1 
        END isCaseSensitive
    FROM 
        sys.fn_helpcollations()
)
SELECT *
FROM collations
WHERE name = CONVERT(varchar, DATABASEPROPERTYEX('yourDatabaseName','collation'));

For more read this MSDN information ;).

TL;DR

Use any. They are almost the same.

Boring answer

As usual, there are pros and cons.

Use std::reverse_iterator:

• When you are sorting custom types and you don't want to implement operator>()
• When you are too lazy to type std::greater<int>()

Use std::greater when:

• When you want to have more explicit code
• When you want to avoid using obscure reverse iterators

As for performance, both methods are equally efficient. I tried the following benchmark:

#include <algorithm>
#include <chrono>
#include <iostream>
#include <fstream>
#include <vector>

using namespace std::chrono;

/* 64 Megabytes. */
#define VECTOR_SIZE (((1 << 20) * 64) / sizeof(int))
/* Number of elements to sort. */
#define SORT_SIZE 100000

int main(int argc, char **argv) {
    std::vector<int> vec;
    vec.resize(VECTOR_SIZE);

    /* We generate more data here, so the first SORT_SIZE elements are evicted
       from the cache. */
    std::ifstream urandom("/dev/urandom", std::ios::in | std::ifstream::binary);
    urandom.read((char*)vec.data(), vec.size() * sizeof(int));
    urandom.close();

    auto start = steady_clock::now();
#if USE_REVERSE_ITER
    auto it_rbegin = vec.rend() - SORT_SIZE;
    std::sort(it_rbegin, vec.rend());
#else
    auto it_end = vec.begin() + SORT_SIZE;
    std::sort(vec.begin(), it_end, std::greater<int>());
#endif
    auto stop = steady_clock::now();

    std::cout << "Sorting time: "
          << duration_cast<microseconds>(stop - start).count()
          << "us" << std::endl;
    return 0;
}

With this command line:

g++ -g -DUSE_REVERSE_ITER=0 -std=c++11 -O3 main.cpp \
    && valgrind --cachegrind-out-file=cachegrind.out --tool=cachegrind ./a.out \
    && cg_annotate cachegrind.out
g++ -g -DUSE_REVERSE_ITER=1 -std=c++11 -O3 main.cpp \
    && valgrind --cachegrind-out-file=cachegrind.out --tool=cachegrind ./a.out \
    && cg_annotate cachegrind.out

std::greater demo std::reverse_iterator demo

Timings are same. Valgrind reports the same number of cache misses.

If you are using the date package, this can be done fairly easily.

library(date)
Date <- c("01/01/2009", "01/01/2010", "01/01/2011", "01/01/2012")
Date <- as.date(Date)
Date
# [1] 1Jan2009 1Jan2010 1Jan2011 1Jan2012
date.mdy(Date)$year
# [1] 2009 2010 2011 2012

## be aware that these are now integers and thus different methods may be invoked:
str(date.mdy(Date)$year)
# int [1:4] 2009 2010 2011 2012
summary(Date)
#     First      Last   
# "1Jan2009" "1Jan2012" 
summary(date.mdy(Date)$year)
#    Min. 1st Qu.  Median    Mean 3rd Qu.    Max. 
#    2009    2010    2010    2010    2011    2012 

for example if you want to get EMAIL ADDRESS from config->store email addresses. You can specify from wich store you will want the address:

$store=Mage::app()->getStore()->getStoreId(); 
/* Sender Name */
Mage::getStoreConfig('trans_email/ident_general/name',$store); 
/* Sender Email */
Mage::getStoreConfig('trans_email/ident_general/email',$store);

The other answers are fine, but this is a little cleaner, in that it only gives the values like you would get from a DISTINCT query, without any cruft from Django.

>>> set(ProductOrder.objects.values_list('category', flat=True))
{u'category1', u'category2', u'category3', u'category4'}

or

>>> list(set(ProductOrder.objects.values_list('category', flat=True)))
[u'category1', u'category2', u'category3', u'category4']

And, it works without PostgreSQL.

This is less efficient than using a .distinct(), presuming that DISTINCT in your database is faster than a python set, but it's great for noodling around the shell.

This error was somewhat misleading - I was loading some DLLs that required x64 architecture to be specified. In the .csproj file:

<PropertyGroup Condition="'$(Configuration)|$(Platform)' == 'Release-ABC|AnyCPU'">
    <OutputPath>bin\Release-ABC</OutputPath>
    <PlatformTarget>x64</PlatformTarget>
</PropertyGroup>

A missing PlatformTarget caused this error.

 <asp:TextBox runat="server" ID="txtPassword" placeholder="Password">

This will work you might some time feel that it is not working due to Intellisence not showing placeholder

You would use off() to remove an event like so:

$("#saveBtn").off("click");

but this will remove all click events bound to this element. If the function with SaveQuestion is the only event bound then the above will do it. If not do the following:

$("#saveBtn").off("click").click(function() { saveQuestion(id); });

I have solved it by adding the following command to my DockerFile

"RUN apt-get update && apt-get install -y libxml2-dev"

On GitHub, you can use HTML directly instead of Markdown:

<a href="url"><img src="http://url.to/image.png" align="left" height="48" width="48" ></a>

This should make it.

If you want load image with a local relative URL as you are doing. React project has a default public folder. You should put your images folder inside. It will work.

I think you can try this Bash debugger: http://bashdb.sourceforge.net/.

I know this question has already been answered, but I decided to add my two cents. Here is code for a merge sort that only uses additional space in the merge operation (and that additional space is temporary space which will be destroyed when the stack is popped). In fact, you will see in this code that there is not usage of heap operations (no declaring new anywhere).

Hope this helps.

    void merge(int *arr, int size1, int size2) {
        int temp[size1+size2];
        int ptr1=0, ptr2=0;
        int *arr1 = arr, *arr2 = arr+size1;

        while (ptr1+ptr2 < size1+size2) {
            if (ptr1 < size1 && arr1[ptr1] <= arr2[ptr2] || ptr1 < size1 && ptr2 >= size2)
                temp[ptr1+ptr2] = arr1[ptr1++];

            if (ptr2 < size2 && arr2[ptr2] < arr1[ptr1] || ptr2 < size2 && ptr1 >= size1)
                temp[ptr1+ptr2] = arr2[ptr2++];
        }   

        for (int i=0; i < size1+size2; i++)
            arr[i] = temp[i];
    }   

    void mergeSort(int *arr, int size) {
        if (size == 1)
            return;

        int size1 = size/2, size2 = size-size1;
        mergeSort(arr, size1);
        mergeSort(arr+size1, size2);
        merge(arr, size1, size2);
    } 

    int main(int argc, char** argv) {
         int num;
         cout << "How many numbers do you want to sort: ";
         cin >> num;
         int a[num];
         for (int i = 0; i < num; i++) {
           cout << (i + 1) << ": ";
           cin >> a[i];
         }   

         // Start merge sort
         mergeSort(a, num);

         // Print the sorted array
         cout << endl;
         for (int i = 0; i < num; i++) {
           cout << a[i] << " ";
         }   
         cout << endl;

         return 0;
    }

All the other answers have described how to explicitly specify the location of the java platform, which is fine if you really want to use a specific version of java. However, if you just want to use the most up-to-date version of jdk, and you have that installed in a "normal" place for your operating system, then the best solution is to NOT specify a jdk location. Instead, let the Netbeans launcher search for jdk every time you start it up.

To do this, do not specify jdkhome on the command line, and comment out the line setting netbeans_jdkhome variable in any netbeans.conf files. (See other answers for where to look for these files.)

If you do this, when you install a new version of java, your netbeans will automagically use it. In most cases, that's probably exactly what you want.

Hard links are useful when the original file is getting moved around. For example, moving a file from /bin to /usr/bin or to /usr/local/bin. Any symlink to the file in /bin would be broken by this, but a hardlink, being a link directly to the inode for the file, wouldn't care.

Hard links may take less disk space as they only take up a directory entry, whereas a symlink needs its own inode to store the name it points to.

Hard links also take less time to resolve - symlinks can point to other symlinks that are in symlinked directories. And some of these could be on NFS or other high-latency file systems, and so could result in network traffic to resolve. Hard links, being always on the same file system, are always resolved in a single look-up, and never involve network latency (if it's a hardlink on an NFS filesystem, the NFS server would do the resolution, and it would be invisible to the client system). Sometimes this is important. Not for me, but I can imagine high-performance systems where this might be important.

I also think things like mmap(2) and even open(2) use the same functionality as hardlinks to keep a file's inode active so that even if the file gets unlink(2)ed, the inode remains to allow the process continued access, and only once the process closes it does the file really go away. This allows for much safer temporary files (if you can get the open and unlink to happen atomically, which there may be a POSIX API for that I'm not remembering, then you really have a safe temporary file) where you can read/write your data without anyone being able to access it. Well, that was true before /proc gave everyone the ability to look at your file descriptors, but that's another story.

Speaking of which, recovering a file that is open in process A, but unlinked on the file system revolves around using hardlinks to recreate the inode links so the file doesn't go away when the process which has it open closes it or goes away.

Call SetContentView(Resource.Layout.Main) after setTheme().

To get or set an attribute of an HTML element, you can use the element.attr() function in jQuery.

To get the href attribute, use the following code:

var a_href = $('selector').attr('href');

To set the href attribute, use the following code:

$('selector').attr('href','http://example.com');

In both cases, please use the appropriate selector. If you have set the class for the anchor element, use '.class-name' and if you have set the id for the anchor element, use '#element-id'.

Pure bash, done in two separate operations:

1. Remove the path from a path-string:

   path=/foo/bar/bim/baz/file.gif
   
   file=${path##*/}  
   #$file is now 'file.gif'
   

2. Remove the extension from a path-string:

   base=${file%.*}
   #${base} is now 'file'.
   

I have built a performance framework that manipulates and graphs millions of datasets, and even then, the javascript calculation latency was on order of tens of milliseconds. Unless you're worried about going over the array size limit, I don't think you have much to worry about.

In case someone is looking for how to configure MongoDB with authentication using docker-compose, here is a sample configuration using environment variables:

version: "3.3"

services:

  db:
      image: mongo
      environment:
        - MONGO_INITDB_ROOT_USERNAME=admin
        - MONGO_INITDB_ROOT_PASSWORD=<YOUR_PASSWORD>
      ports:
        - "27017:27017"

When running docker-compose up your mongo instance is run automatically with auth enabled. You will have a admin database with the given password.

Try this:

String urle = HOST + url + value;

Then return the values from:

urle.replace(" ", "%20").trim();

first you need to add 2 columns to datagrid. you may do it at design time. see Columns property. then add rows as much as you need.

My way of achieving this is by creating ZipInputStream wrapping class that would handle that would provide only the stream of current entry:

The wrapper class:

public class ZippedFileInputStream extends InputStream {

    private ZipInputStream is;

    public ZippedFileInputStream(ZipInputStream is){
        this.is = is;
    }

    @Override
    public int read() throws IOException {
        return is.read();
    }

    @Override
    public void close() throws IOException {
        is.closeEntry();
    }

}

The use of it:

    ZipInputStream zipInputStream = new ZipInputStream(new FileInputStream("SomeFile.zip"));

    while((entry = zipInputStream.getNextEntry())!= null) {

     ZippedFileInputStream archivedFileInputStream = new ZippedFileInputStream(zipInputStream);

     //... perform whatever logic you want here with ZippedFileInputStream 

     // note that this will only close the current entry stream and not the ZipInputStream
     archivedFileInputStream.close();

    }
    zipInputStream.close();

One advantage of this approach: InputStreams are passed as an arguments to methods that process them and those methods have a tendency to immediately close the input stream after they are done with it.

not sure if it'll work in your scenario, but try adding the following to your web.config under <system.web>:

  <system.web>
    <customErrors mode="Off" />
  ...
  </system.web>

works in my instance.

CustomErrors mode="Off"

You need to scp something somewhere. You have scp ./styles/, so you're saying secure copy ./styles/, but not where to copy it to.

Generally, if you want to download, it will go:

# download: remote -> local
scp user@remote_host:remote_file local_file 

where local_file might actually be a directory to put the file you're copying in. To upload, it's the opposite:

# upload: local -> remote
scp local_file user@remote_host:remote_file

If you want to copy a whole directory, you will need -r. Think of scp as like cp, except you can specify a file with user@remote_host:file as well as just local files.

Edit: As noted in a comment, if the usernames on the local and remote hosts are the same, then the user can be omitted when specifying a remote file.

int *array = new int[n];

It declares a pointer to a dynamic array of type int and size n.

A little more detailed answer: new allocates memory of size equal to sizeof(int) * n bytes and return the memory which is stored by the variable array. Also, since the memory is dynamically allocated using new, you've to deallocate it manually by writing (when you don't need anymore, of course):

delete []array;

Otherwise, your program will leak memory of at least sizeof(int) * n bytes (possibly more, depending on the allocation strategy used by the implementation).

I don't believe the expression is sensical as it is.

Elvis means "if truthy, use the value, else use this other thing."

Your "other thing" is a closure, and the value is status != null, neither of which would seem to be what you want. If status is null, Elvis says true. If it's not, you get an extra layer of closure.

Why can't you just use:

(it.description == desc) && ((status == null) || (it.status == status))

Even if that didn't work, all you need is the closure to return the appropriate value, right? There's no need to create two separate find calls, just use an intermediate variable.

Another solution could be using in JSP: <input type="hidden" id="jsonBom" value='${jsonBom}'/>

and getting the value in Javascript with jQuery:

var jsonBom = $('#jsonBom').val();

For me, it just was that service console restart didn't work after tomcat ran into an error. Only stop/start brought it back.

As your content is 24dp x 24dp you should use 24dp icon. And then set android:scaleType="center" in your ImageButton to avoid auto resize.

Warning: this is a dangerous method! It abuses the i/o buffers in linux and with specific options of buffering it manages to work on small files. It is an interesting curiosity. But don't use it for a real situation!

Besides the -i option of sed you can use the tee utility.

From man:

tee - read from standard input and write to standard output and files

So, the solution would be:

sed s/STRING_TO_REPLACE/STRING_TO_REPLACE_IT/g index.html | tee | tee index.html

-- here the tee is repeated to make sure that the pipeline is buffered. Then all commands in the pipeline are blocked until they get some input to work on. Each command in the pipeline starts when the upstream commands have written 1 buffer of bytes (the size is defined somewhere) to the input of the command. So the last command tee index.html, which opens the file for writing and therefore empties it, runs after the upstream pipeline has finished and the output is in the buffer within the pipeline.

Most likely the following won't work:

sed s/STRING_TO_REPLACE/STRING_TO_REPLACE_IT/g index.html | tee index.html

-- it will run both commands of the pipeline at the same time without any blocking. (Without blocking the pipeline should pass the bytes line by line instead of buffer by buffer. Same as when you run cat | sed s/bar/GGG/. Without blocking it's more interactive and usually pipelines of just 2 commands run without buffering and blocking. Longer pipelines are buffered.) The tee index.html will open the file for writing and it will be emptied. However, if you turn the buffering always on, the second version will work too.

Using jquery you might do something like this:

// To disable 
$('#targetDiv').children().attr('disabled', 'disabled');

// To enable
$('#targetDiv').children().attr('enabled', 'enabled');

Here's a jsFiddle example: http://jsfiddle.net/monknomo/gLukqygq/

You could also select the target div's children and add a "disabled" css class to them with different visual properties as a callout.

//disable by adding disabled class
$('#targetDiv').children().addClass("disabled");

//enable by removing the disabled class
$('#targetDiv').children().removeClass("disabled");

Here's a jsFiddle with the as an example: https://jsfiddle.net/monknomo/g8zt9t3m/

you can use the context of the view that did the calling. Example:

Button orderButton = (Button)findViewById(R.id.order);

orderButton.setOnClickListener(new View.OnClickListener() {

  @Override
  public void onClick(View view) {
    Intent intent = new Intent(/*FirstActivity.this*/ view.getContext(), OrderScreen.class);
    startActivity(intent);
  }

});

You can return the same value from several matches:

SELECT
  CASE c.Number
    WHEN '1121231' THEN 1
    WHEN '31242323' THEN 1
    WHEN '234523' THEN 2
    WHEN '2342423' THEN 2
  END AS Test
FROM tblClient c

This will probably result in the same execution plan as Martins suggestion, so it's more a matter of how you want to write it.

CREATE TRIGGER sampleTrigger
    ON database1.dbo.table1
    FOR DELETE
AS
    DELETE FROM database2.dbo.table2
    WHERE bar = 4 AND ID IN(SELECT deleted.id FROM deleted)
GO

In my case I just had to add a name to the String. In first instance I just had a space in between the brackets

private static final String TAG = " ";

but after adding a name it worked perfectly.

private static final String TAG = "oncreate";

I use Windows Server 2012 for hosting for a long time and it just stop working after a more than years without any problem. My solution was to add public IP address of the server to list of relays and enabled Windows Integrated Authentication.

I just made two changes and I don't which help.

Go to IIS 6 Manager

Select properties of SMTP server

On tab Access, select Relays

Add your public IP address

Close the dialog and on the same tab click to Authentication button.

Add Integrated Windows Authentication

Maybe some step is not needed, but it works.

I ended up leaving the common properties from the SELECT queries and making a second SELECT query later on in the page. I used a php IF command to call for different scripts depending on the first SELECT query, the scripts contained the second SELECT query.

I am using mac airbook open your terminal and type

 sudo ln -s /Applications/Sublime\ Text.app/Contents/SharedSupport/bin/subl /usr/bin/subl

Then type simple subl and file name

 subl index.py

.attr() sometimes doesn't work in older jQuery versions, but you can use .prop():

$('select#ddlCountry option').each(function () {
    if ($(this).text().toLowerCase() == co.toLowerCase()) {
        $(this).prop('selected','selected');
        return;
    }
});

Hacky way:

You could increase the session timeout programmatically when a large up-/download is expected.

session.setMaxInactiveInterval(TWO_HOURS_IN_SECONDS)

When the process ends, you could set the timeout back to its default.

But.. when you are on Java EE, and the up-/download doesn't take a complete hour, the better way was to run the tasks asynchronous (via JMS e.g.).

I had the same issue, virtualenv was pointing to an old python path. Fixing the path resolved the issue:

$ virtualenv -p python2.7 env
-bash: /usr/local/bin/virtualenv: /usr/local/opt/python/bin/python2.7: bad interpreter: No such file or directory

$ which python2.7
/opt/local/bin/python2.7

# needed to change to correct python path
$ head  /usr/local/bin/virtualenv
#!/usr/local/opt/python/bin/python2.7 <<<< REMOVED THIS LINE
#!/opt/local/bin/python2.7 <<<<< REPLACED WITH CORRECT PATH

# now it works:
$ virtualenv -p python2.7 env
Running virtualenv with interpreter /opt/local/bin/python2.7
New python executable in env/bin/python
Installing setuptools, pip...done.

This is pretty easy with ProcessLifecycleOwner

Add these dependencies

implementation "android.arch.lifecycle:extensions:$project.archLifecycleVersion"
kapt "android.arch.lifecycle:compiler:$project.archLifecycleVersion"

In Kotlin:

class ForegroundBackgroundListener : LifecycleObserver {


    @OnLifecycleEvent(Lifecycle.Event.ON_START)
    fun startSomething() {
        Log.v("ProcessLog", "APP IS ON FOREGROUND")
    }

    @OnLifecycleEvent(Lifecycle.Event.ON_STOP)
    fun stopSomething() {
        Log.v("ProcessLog", "APP IS IN BACKGROUND")
    }
}

Then in your base activity:

override fun onCreate() {
        super.onCreate()

        ProcessLifecycleOwner.get()
                .lifecycle
                .addObserver(
                        ForegroundBackgroundListener()
                                .also { appObserver = it })
    }

There's no need to write a custom directive. Angular's documentation is good but not complete. In fact, there is a directive called ngRequired, that takes an Angular expression.

<input type='email'
       name='email'
       ng-model='contact.email' 
       placeholder='[email protected]'
       ng-required='!contact.phone' />

<input type='text'
       ng-model='contact.phone'             
       placeholder='(xxx) xxx-xxxx'
       ng-required='!contact.email' />

java.lang.VerifyError means your compiled bytecode is referring to something that Android cannot find. This verifyError Issues me only with kitkat4.4 and lesser version not in above version of that even I ran the same build in both Devices. when I used jackson json parser of older version it shows java.lang.verifyerror

compile 'com.fasterxml.jackson.core:jackson-databind:2.2.+'
compile 'com.fasterxml.jackson.core:jackson-core:2.2.+'
compile 'com.fasterxml.jackson.core:jackson-annotations:2.2.+'

Then I have changed the Dependancy to the latest version 2.2 to 2.7 without the core library, then it works. which means the Methods and other contents of core is migrated to the latest version of Databind2.7. This fix my Issues.

compile 'com.fasterxml.jackson.core:jackson-annotations:2.7.0-rc3'
compile 'com.fasterxml.jackson.core:jackson-databind:2.7.0-rc3'

Availability to instance methods

• Class instance variables are available only to class methods and not to instance methods.
• Class variables are available to both instance methods and class methods.

Inheritability

• Class instance variables are lost in the inheritance chain.
• Class variables are not.

class Vars

  @class_ins_var = "class instance variable value"  #class instance variable
  @@class_var = "class variable value" #class  variable

  def self.class_method
    puts @class_ins_var
    puts @@class_var
  end

  def instance_method
    puts @class_ins_var
    puts @@class_var

Vars.class_method

puts "see the difference"

obj = Vars.new

An example of how to use "continue" labels in Java is:

public class Label {
    public static void main(String[] args) {
        int temp = 0;
        out: // label
        for (int i = 0; i < 3; ++i) {
            System.out.println("I am here");
            for (int j = 0; j < 20; ++j) {
                if(temp==0) {
                    System.out.println("j: " + j);
                    if (j == 1) {
                        temp = j;
                        continue out; // goto label "out"
                    }
                }
            }
        }
        System.out.println("temp = " + temp);
    }
}

Results:

I am here // i=0
j: 0
j: 1
I am here // i=1
I am here // i=2
temp = 1

There are two ways. In case of doubt, you can always just try it. If it does not work, you can add extra braces to make sure, like that:

if not ((u0 <= u) and (u < u0+step)):

cat ~/.ssh/id_rsa.pub

then you can copy your ssh key

You can use this OverlayContainer. The trick is to use absolute with 100% size. Check below an example:

// @flow

import React from 'react'
import { View, StyleSheet } from 'react-native'

type Props = {
  behind: React.Component,
  front: React.Component,
  under: React.Component
}

// Show something on top of other
export default class OverlayContainer extends React.Component<Props> {
  render() {
    const { behind, front, under } = this.props

    return (
      <View style={styles.container}>
        <View style={styles.center}>
          <View style={styles.behind}>
            {behind}
          </View>
          {front}
        </View>
        {under}
      </View>
    )
  }
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    alignItems: 'center',
    height: '100%',
    justifyContent: 'center',
  },
  center: {
    width: '100%',
    height: '100%',
    alignItems: 'center',
    justifyContent: 'center',
  },
  behind: {
    alignItems: 'center',
    justifyContent: 'center',
    position: 'absolute',
    left: 0,
    top: 0,
    width: '100%',
    height: '100%'
  }
})

The most robust mechanism for listing all resources in the classpath is currently to use this pattern with ClassGraph, because it handles the widest possible array of classpath specification mechanisms, including the new JPMS module system. (I am the author of ClassGraph.)

How to know the name of the JAR file where my main class lives?

URI mainClasspathElementURI;
try (ScanResult scanResult = new ClassGraph().whitelistPackages("x.y.z")
        .enableClassInfo().scan()) {
    mainClasspathElementURI =
            scanResult.getClassInfo("x.y.z.MainClass").getClasspathElementURI();
}

How can I read the contents of a directory in a similar fashion within a JAR file?

List<String> classpathElementResourcePaths;
try (ScanResult scanResult = new ClassGraph().overrideClasspath(mainClasspathElementURI)
        .scan()) {
    classpathElementResourcePaths = scanResult.getAllResources().getPaths();
}

There are lots of other ways to deal with resources too.
